The 35-year-old actress split with husband Sam Mendes in 2010, and said that although she was afraid of being alone to begin with, she actually quite enjoys it.
She told Vogue, 'To be in this place now where I can say I really like this space, I really need to not have anyone around... it's a surprise to discover that I like being on my own.
'Experiencing those moments of being alone... is a very, very weird flooring and exposing position to be in when you're just not used to it. And it's not just being in a relationship. It's also the fact that I grew up in a family full of people.
'But I've never been lonely. And with my kids Mia and Joe that remains the case.'
